Buries the unit underground. Burrowed units are unable to move or attack, but they cannot be seen without detection.

Ability

Rapid Regeneration

The Roach regenerates life very quickly while burrowed.

In the years following the Brood War, Kerrigan became obsessed with the genetic codes of species with hyper-regenerative properties. The most impressive example was the unassuming acidic Zantar Slug living in the humid, mountainous depths of Garrxax. This tiny slug was capable of healing itself at rapid rates, and it also excreted mucus that could eat through neosteel. Consequently it was quickly assimilated into the Swarm. Thus the Roach was evolved, a creature that can heal itself rapidly and deliver deadly ranged acid blasts. In a one-on-one battle, not much can stand against this regenerating monstrosity.

Employ high-damage units such as Siege Tanks and Banshees. Their damage output will allow them to take the Roaches down quickly.

Use Ravens to help spot burrowed Roaches and prevent them from sneaking up on Siege Tanks in Siege Mode.

Utilize Marauders since they deal bonus damage against the Roach’s armor and also significantly outrange them. It’s possible to kite the Roaches using the Concussive Shells upgrade which slows down targets hit by the Marauder.
